(Cl. 236-352) It is previously known in automobiles to control au- `cally the temperature of the cooling iiuid of inperature being increased, and vice versa, said control device being, in order to cause transmission of its movethe fact that said tie bar is in the form of a slide vertically displaceable on a lateral side-surface of said frame and is formed with guide slots, each vane pivot is excontrol device.

The invention will now be described more in detail in conjunction with an embodiment thereof illustrated in having a web portion 20a joining side walls 2Gb and 20c.

portions 20a facing inwardly of the frame.

otally mounted at their ends in openings 23 in the web through the openings 23 1n the web portions 20a and are bent over into a substantially U-shape.

In at least one upper corner of the rectangular frame,

nited States Patent 2,751,154 Patented June 19, 1956 the vertical side member 20 is broadened into a platelike end thereof and a upwardly extending leg 8b on the other end thereof.

Reinforcement bars 16 are secured to the web portion inside and adjacent to one of the side walls of a vertical channel member. The mounting pivots 3 extend through for the mounting pivots 3 in the web portion 20a of the frame l. The said slide portions 9 and 10, therefore,

control device 6 to be extended causing displacement of the slides 9 and 10.

The slides 9 and 10 are, as previously mentioned, provided with openings in the form of guide slots, one for lower group of guide slots, formed in the slide 9, consists of a lower portion 14 extending longitudinally of the slide 9, and an upper portion 15 extending transversely extending portions 13, 1S of the guide slots depart from the corresponding longitudinal portions 12, 14 in a direction leading away from the corresponding vane pivots 3. The transversely extending portions of the guide slots may extend perpendicularly to the longitudinal direction of the slides, as shown at-13, but itis preferred, in order to facilitate the pivot end portions 4 sliding into the same, that they extend at an angle to said longitudinal direction, as vshown at 15.

In the embodiment illustrated, the longitudinally extending portions 12, 14 of the guide slots are defined partly by a lateral edge of recesses made, in one longitudinal edge of the slides 9 and 10, and partly by the straight longitudinal edge of the reinforcement 16 which serves as a guide member along which the slides are longitudinally displaceable in the manner illustrated.

Further, in the embodiment illustrated, the shutter vanes 2 and slots for the bent over ends of the pivots 3 are thus divided into two sets and so arranged that the upper shutter vane set, comprising in this instance four vanes which are made shorter than theV lower vanes in order to accommodate the recess for the control device' 6, will be opened in advance of the lower set, theV latter comprising' in this instance seven vanes. lt is for this purpose that the slots are made different in the two sets. In the upper set the transverse portion 13 of the guide slot is adapted m a first portion of the opening movement of the slide 1,0 to move the pivot end portion 4 causing the latter to rock due to the fact that the pivot' end portion 4 projects into the transverse portion 13 of the slot, whereby the shutter vane mounted on this pivot will be angularly adjusted into its open position. Thereafter the longitudinal portion 12 of the slot will allow continued displacement of the slide which movement is unobstructed by the pivot end portion 4 projecting into the guide slot. In the lower set the longitudinally extending portion 14 is adapted to permit a limited opening movement of the slide 9 without actuation of the lower shutter vane set, and the transversely extending portion 15 is adapted upon termination of the opening movement of the slide 10 to move the' pivotY end portion 4 projecting into the same and thereby cause opening of the lower shutter vane set.

It will be understood that the embodiment illustrated' and described is to be considered merely by way of eX- ample, and that the invention may be varied within the scope of the appended claims.

What we claim and desire to secure by Letters Patent l. In a mechanism for automatically controlling the cooling liquid temperature of internal combustion engines for vehicles, said mechanism having disposed in front of the radiator of said vehicle a substantially rectangular frame with substantially vertical side channel members connected by top and bottom members, said vertical members having their web portions facing inwardly of the frame with a plurality of openings therein, shutter vanes mounted in said frame having pivots on the ends thereof extending through the openings in said web portions, and regulator means on said frame having a portion thereof movable in dependence on the temperature of the cooling liquid, that improvement comprising at least one reinforcement bar having one straight edge mounted on said web portion adjacent to one of the channel sidewalls and having a plurality of openings therein throughwhich the pivots on said vanes extend, and at least one slide slidably mounted against said web portion between said reinforcement bar and a side Wall of the vertical frame member and having al plurality of guide slots therein, the ends of said pivots being bent over and engaged inI said openings, and said slide cnnected to said regulator means and movable thereby in response to a temperature change of said cooling liquid.

2. The improvement as claimed in claim 1 in which at least one of the vertical side members of the frame is broadened near the top to form a corner plate on which said regulator means is mounted, saidcorner plate having a web portion on the inner edge thereof perpendicular to said plate, and in which there are two' of said .re-

inforcement bars, one on the web portion of the vertical member of said frame and one on the web portion of the corner plate, reinforcement bar on the web portion of the vertical member of said frame' and said frame, and one between the reinforcement bar on the web of said corner plate and saidl 'corner plate, and said openings in said slides are in the form of slots, each slot in the slide on the web of the corner platecomprising a lower, transversely extending portion and an upper, longitudinally extending portion, and each slot in the slide on the web of the'vertical member of the frame comprising a lower, longitudinally extending portionv and an upper, transverselyl extending portion, the transversely extending portions of said slots departing from the longitudinally extending portions thereof in a direction away from saidl pivots.

3. The improvement as claimed in claim 2, said slides having recesses in the longitudinal edges thereof adja-` cent 'the edge of said reinforcement bars, thel said longitudinally extending portions of said slots being defined partly by a lateral edge of said recesses and partly by the edge of said reinforcement bars beneath which said slides are Slidable.
